Technical Field

[0002] During mattress production, manufacturers compress and roll mattresses to facilitate transportation. This process involves rolling the mattresses into long, cylindrical shapes, minimizing packaging and shipping volume. This process is typically accomplished using a roll wrapping machine.

[0043] Reference Figures 1 to 7 As shown, an embodiment of the present invention is a mattress rolling machine, which is used for mattress rolling operations and includes: a frame, a rolling mechanism 200 and a lifting mechanism 300.

[0044] Reference Figure 1 and Figure 2 As shown, the frame includes an upper frame 110 and a lower frame 120 spaced apart from each other, the wrapping mechanism 200 is connected to the lower frame 120 and is located below the upper frame 110, the wrapping mechanism 200, the upper frame 110 and the lower frame 120 jointly define a wrapping space 130, the lifting mechanism 300 is transmission-connected to the upper frame 110 to drive the upper frame 110 closer to the wrapping mechanism 200 to reduce the wrapping space 130, or drive the upper frame 110 away from the wrapping mechanism 200 to increase the wrapping space 130, the wrapping mechanism 200 has a limiting effect on the lifting and lowering stroke of the upper frame 110, that is, the setting height of the wrapping mechanism 200 has a limiting effect on the adjustment range of the wrapping space 130.

[0045] Reference Figure 3 and Figure 4 As shown, the wrapping mechanism 200 includes a first frame 210, a first roller 220, a second frame 230, a second roller 240, a flipping drive 270 and a swinging drive 250. The first frame 210 is rotatably connected to the lower frame 120, the first roller 220 is rotatably connected to the first frame 210, the second frame 230 is rotatably connected to the end of the first frame 210 away from the lower frame 120, the second roller 240 is rotatably connected to the second frame 230, the flipping drive 270 is transmission-connected to the first frame 210 for driving the first frame 210 to flip up and down relative to the lower frame 120, and the swinging drive 250 is transmission-connected to the second frame 230 for driving the second frame 230 to flip up and down relative to the first frame 210.

[0046] Reference Figure 2 、 Figure 3 and Figure 4As shown, the first frame 210 of the mattress rolling machine is rotatably connected to the lower frame 120, and the first roller 220 is rotatably connected to the first frame 210. Under the driving action of the flip drive 270, the first frame 210 can be flipped up and down relative to the lower frame 120, that is, the setting height of the rolling mechanism 200 is adjusted in one level. The second frame 230 is rotatably connected to the end of the first frame 210 away from the lower frame 120, and the second roller 240 is rotatably connected to the second frame 230. Under the driving action of the swing drive 250, the first frame 210 can be flipped up and down relative to the lower frame 120, that is, the setting height of the rolling mechanism 200 is adjusted in one level. The second frame 230 is configured to be able to flip up and down relative to the first frame 210, i.e., the height of the rolling mechanism 200 is adjusted in a two-level manner. The first roller 220 and the second roller 240 can guide the mattress input into the rolling space 130, so that the mattress is rolled back into a cylinder. The mattress rolling machine can realize the two-level adjustment of the rolling mechanism 200 in the height direction through the connection between the first frame 210 and the second frame 230, which can effectively increase the adjustment range of the rolling space 130 and help reduce the restriction on the size of the mattress.

[0047] Reference Figure 2 、 Figure 3 and Figure 4 As shown, compared to conventional rolling machines, the inner diameter of the rolling space 130 of this mattress rolling machine can be adjusted to a smaller size. This allows the mattress to be rolled initially within the smaller rolling space 130, resulting in a smaller cavity in the cylindrical body of the mattress, which helps reduce the transport volume of the rolled mattress. Because the inner diameter of the rolling space 130 can be adjusted to a smaller size, smaller mattresses can be rolled within the rolling space 130. Compared to the larger inner diameter of the rolling space 130 of conventional rolling machines, the mattress rolling machine provided by this embodiment of the utility model can achieve the rolling of smaller mattresses.

[0048] Reference Figure 2 、 Figure 3 and Figure 4As shown, when in use, the mattress rolling machine can first make the second frame 230 flip up or down relative to the first frame 210 in advance according to the size of the mattress to be rolled through the operation of the swing mechanism, that is, change the relative position relationship between the second frame 230 and the first frame 210. When the mattress is rolled, only through the operation of the flip drive 270, the first frame 210 is driven to flip up or down relative to the lower frame 120, thereby achieving a guiding effect on the mattress to assist in the rewinding of the mattress, and the setting of the rolling mechanism 200 is conducive to limiting the problem of the mattress falling out of the rolling space 130 before the rolling is completed. Alternatively, when the mattress is being rolled, the mattress rolling machine drives the first frame 210 to flip upward or downward relative to the lower frame 120 through the operation of the flipping drive 270, and simultaneously realizes the flipping of the second frame 230 relative to the first frame 210 through the operation of the swing drive 250, and cooperates with the operation of the lifting mechanism 300 to make the inner diameter of the rolling space 130 gradually increase as the outer diameter of the column formed by the mattress increases.

[0049] Reference Figure 2 、 Figure 3 and Figure 4 As shown, it is understandable that the mattress rolling machine further includes a plurality of connecting members 400, the connecting member 400 includes a first ring sleeve 410 and a second ring sleeve 420 connected to each other, the first ring sleeve 410 is sleeved on the outer periphery of the first roller 220 and is rotatably connected to the first roller 220, and the second ring sleeve 420 is sleeved on the outer periphery of the second roller 240 and is rotatably connected to the second roller 240, and the first ring sleeve 410 is rotatably connected to the first roller 220 to realize the second frame 230 and the first frame 230 being connected. The rotational connection of the frame 210, under the driving action of the swing drive 250, can change the second frame 230 to swing around the rotational connection between the first ring sleeve 410 and the first roller 220, thereby further adjusting the setting height of the winding mechanism 200. The setting height of the winding mechanism 200 has a limiting effect on the adjustment range of the winding space 130. The second ring sleeve 420 is rotationally connected to the second roller 240, thereby avoiding the problem of the connecting member 400 hindering the rotation of the second roller 240.

[0050] Reference Figure 2 、 Figure 3 and Figure 4As shown, multiple connectors 400 are arranged at intervals along the length of the second roller 240. The mattress rolling machine, through the connection of the multiple connectors 400, can achieve multi-point connection between the first roller 220 and the second roller 240, thereby improving the connection stability between the second roller 240 and the first roller 220. The mattress rolling machine, through the connection between the first frame 210 and the second frame 230, can achieve two-level height adjustment of the rolling mechanism 200, effectively expanding the adjustment range of the rolling space 130 and reducing the size restrictions on the mattress.

[0051] Reference Figure 2 、 Figure 3 and Figure 4 As shown, specifically, each connecting member 400 corresponds to two bearing settings, one of which is provided on the inner circumference of the first ring sleeve 410, and the first ring sleeve 410 is rotatably connected to the first roller 220 through the bearing, which is conducive to achieving smooth rotation of the connecting member 400 and the first roller 220, and the other bearing is provided on the inner circumference of the second ring sleeve 420, and the second ring sleeve 420 is rotatably connected to the second roller 240 through the bearing, which is conducive to avoiding the problem of the connecting member 400 hindering the rotation of the second roller 240.

[0052] Reference Figure 2 、 Figure 3 and Figure 4 As shown, it is understandable that the swing drive 250 includes a first fixed end 251 and a first movable end 252 that can be relatively retracted. The first fixed end 251 is rotatably connected to the first frame 210, and the first movable end 252 is rotatably connected to the second frame 230.

[0053] Reference Figure 2 、 Figure 3 and Figure 4 As shown, when the swing mechanism is operating, the relative extension and contraction of the first fixed end 251 and the first movable end 252 can drive the second frame 230 to swing relative to the first frame 210, so that the second frame 230 can flip up and down relative to the first frame 210, that is, realize the secondary adjustment of the rolling mechanism 200. When the swing mechanism is not operating, and the flipping mechanism is operating, under the connection action of the swing mechanism, the second frame 230 is caused to flip synchronously with the first frame 210 to adjust the setting height of the rolling mechanism 200, so as to realize the adjustment of the rolling space 130, and through the first roller 220 connected to the first frame 210 and the second roller 240 connected to the second frame 230, the mattress input into the rolling space 130 is guided, so that the mattress is gradually rolled back into a cylinder, that is, the rolling operation of the mattress is realized.

[0054] Reference Figure 2 、 Figure 3 and Figure 4As shown, it can be understood that, specifically, the flip drive 270 includes a second fixed end and a second movable end that can be relatively extended and retracted, the second fixed end is rotatably connected to the lower frame 120, and the second movable end is rotatably connected to the first frame 210, and the second fixed end is extended and retracted relative to the second movable end, thereby applying a push or pull force to the first frame 210, so that the first frame 210 is flipped up or down relative to the lower frame 120, so as to achieve the adjustment of the setting height of the wrapping mechanism 200, and cooperate with the driving action of the lifting mechanism 300 to reduce or increase the size of the wrapping space 130.

[0055] It should be noted that both the flip drive 270 and the swing drive 250 can be linear drive mechanisms such as air cylinders, oil cylinders, and linear motors.

[0056] Reference Figure 2 、 Figure 3 and Figure 5 As shown, it can be understood that, specifically, in order to enhance the guiding effect of the first roller 220 and the second roller 240 on the mattress and avoid the problem of the mattress being stuck at the junction of the wrapping mechanism 200 and the lower frame 120, which leads to the failure of wrapping, the mattress wrapping machine also includes a first rotary drive, the wrapping mechanism 200 also includes a first chain 262 and at least two sprockets, the two first sprockets 261 are coaxially connected to the first roller 220 and the second roller 240 respectively, and the first chain 262 is wound around the two first sprockets 261, and the first chain 262 is connected to the at least two first sprockets. 261, so as to realize the synchronous connection of the two first sprockets 261, that is, to realize the synchronous connection of the first roller 220 and the second roller 240. Under the driving action of the first rotary drive, the synchronous rotation of the first roller 220 and the second roller 240 is realized.
